Sand, which is made of tiny grains of rock (usually quartz) has many uses. Bags full of sand keep rivers from jumping their banks and flooding the surrounding area. Sand sprinkled on icy sidewalks and roads can keep people and cars from slipping. Sand can even be used as a mold for making candles. Here's how:

Step 1: With help from your parents or an adult, melt some wax (this is a good way to reuse old candles) in an old pan or an empty coffee can.

Step 2: Fill a box with damp sand.

Step 3: Use your fist to hollow out some holes in the sand.

Step 4: Put a small candle in the center of each hole. The candles' wicks should reach the tops of the holes.

Step 5: Fill each hole around the small candle with melted wax. Be careful not to burn yourself with the hot wax!

Step 6: Let your candles sit overnight, then dig them out of the sand.

To make a candle with legs: Poke your finger down into the sand in three places after you have made your fist depression. You will have a flat-topped candle that stands on three wax legs.
